ADJUSTABLE SHOVEL-BLOGK FOR PLOWS.

$PEC1'FIGATION forming part of-Letters Patent No. 342,058, dated May 18,1886.

Application filed January 5, 1886. Serial No. 187,717. (No model.)

To all whom it may concern.-

Be it known that I, J OHN R. WILLrAMs, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Adjustable Shovel-Blocks for Plows; and Ihereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, wherein-Figure l is a top view of a block embodying my invention, showing themeans for detaclr ably securing the plow to the block, and for adjustingthe block on the standard so as to set the shovel at any desired angleand adjust it accurately with relation to any other shovel of the gang.Fig. 2 is a vertical central sec tion of the same. 3 is a detached Viewof the washer-bloek used with the bolt which secures the shovel to theshovel-block.

Like letters refer to like parts wherever they occur.

My present invention relates to the construction of shovel-blocks forsecuring the shovel to the plow-standard.

It is a very desirable thing that the user should have an accurate guidefor setting any shovel to the desired angle and adjusting the othershovels into proper relation thereto, as on such adjustment depends thedraft and effective operation of the plows. It is also desirable to beable to detach and attach the shovels readily without moving the plow tothe shop. Toaccomplishtheadvantagesspccified I provide a sleeve-journalbearing with graduated flange for the standard and a sleeve block withcorresponding graduated flange for the shovel, together with means forlocking the sleeves after adjustment, and this constitutes the firstfeature of my invention. The shovel I secure to the shovel-block bymeans of a key and bolt, so that the two are readily separable, and thisconstitutes the second feature of my invention. The means which I preferfor graduating and locking the sleevejournal and sleeve-block are aseries of perforations equally distant in either flange, but atdifferent distances or different intervals in the two flanges, whichenables at least two perforations-one in each flange-4o register withvery slight movement of the sleeve-block, whereby very fine adjustmentsof the shovel can be had, and this constitutes a third feature of myinvention.

There are other minor features which will hereinafter more fully appear.

I will now proceed to describe my invention more fully, so that othersskilled in the art to which it appcrtains may apply the same.

In the drawings, A indicates the standard of a plow, and which may be ofany of the sevcral well-known characters or materials commonly employedfor the purpose.

B indicates a sleeve-journal adapted to be rigidly secured thereon. Thesocket of this sleeve journal or hearing will conform to the crosssection of the standard to which it is to be attached. If the standardis ofiron, the socket may be polygonal, and if the standard is of woodit may be a sleeve or hollow cylinder, as shown. This journal-sleeve mayhave a flange, b, which will not only support the sleeve shovel-block,but serve as the location of the graduated scale to indicate the extentof movement of the shovel-block in adjusting the same.

In the present instance I make the holes of the locking-cotter thescale, by arranging said' hole 0 at regular intervals, say,seven-twelfths of an inch apart, and arranging similar cotter-holes, d,in a flange of the sleeve shove1- block, the latter, say, sixtwelfths ofan inch apart, so that at least two cotter-holes must register at everyone-twelfth of an inch movement of the rotary sleeve shovelblock.

The above figures are given for purposes of illustration,and not forlimitation,as any other scale maybe employed at the will of the user, solong as a definite scale is provided. The flange b may be strengthenedby ribs, (indicated in dotted lines at c, Fig. 2.)

0 indicates a rotating or sleeve shovel-block having a curved orotherwise suitablyshaped bearing-face, d, for the shovel, and a key seator slot, f, and elongated bolt-hole r ,for securing the shovel to theblock. This rotating sleeve-block has a flange, (1 corresponding to thatof the sleevc-journal B, upon which it bears or finds a rest when thepart-s are in use, and said flange is perforated atintervals for acotter, as hereinbefore described.

' D indicates the shovel provided with a suitable rearward-projectingT-headed key, k, adapted to fit the slotted key-seat f, so as to beretained therein and hold the shovel while permitting the use ofdifferent shovels having varying distances between the key 70 andretaining-bolt Z, as will frequently happen. Z1

indicates abolt which passes through the elongated slot or bolt-hole g,and through a washer or block, E, which is convex to fit the rear ofshovel-block 0 below the sleeve, and to form a stop for the sleeve-blockand asquare or flat seat for the nut F, which secures the shovel. Itwill be noted that this block or washer E locks the rotatingsleeve-block O and prevents it from being thrust up on thejournal-sleeve, so that the only motion of the sleeveblock O is a rotaryone.

When in use, the sleeve-journal B is secured to the end of theplow-standard A, and the shovel D is attached to the rotatingsleeveblock 0 by inserting its key is in the key-seat f of the block andpassing the bolt Z through the slot or bolt-hole g and washer-block Eand tightening the parts by means of nut F.

In order-to adjust the angle of the shovel to the line of draft, thecotter K is withdrawn and the sleeve-block rotated on the sleeve-journalthe desired distance in either direction and the cotter again inserted.The relation of the holes in the two flanges b and (I will indicate theexact adjustment and enable the user to adjust any or' all other shovelsof the gang to correspond.

I am aware that a shovel-plow has been rendered adjustable by means of ahollow coneshaped shovel-block having indentations or teeth on itsinterior, which was employed in conjunction with a conical castinghaving teeth which mesh with the indentations on the interior of thehollow cone, and also that a scraper has been adjustably secured to astandard by means of a foot or spread portion of the standard, aprojecting pin thereon, and an indented washer interposed between thestandard and plow; and I do not herein claim either of the aboveconstructions, first, because there'rn a bolt and a nut are required toadjustably connect the standard, which nut is liable to loss, thusrendering the parts inoperative; secondly, because the standard does notsuspend and retain the shovel-block and shove], so as to preventseparation of the parts when the locking devices are lost or displaced;and, third, because the construction is mechanically different.

Having thus described the nature, operation, and advantages of myinvention, what I claim, and desire to secure by Letters Patent, isv 1.In a shovel-block for plows, the combination,'with a journal on thestandard, said journal having a perforated flange, of a rotatableshovel-block having a perforated flange, the intervals between theperforations differing from those of the journal-flange, substantiallyas and for the purposes specified.

2. The combination, with a shovel block having a T-key seat, and anelongated boltslot, of a shovel-plow having a looking or T key, and abolt for securing the shovel t0 the block, substantially as and for thepurposes specified.

3. The combination, with a standard-journal having a flange, and sleeveshovel-block having aflange, a T-key seat, and a bolt-hole, of

a stop-washer and abolt for both securing the shovel to the block andpreventing the block from riding up on the standard, substantially asand for the purposes specified.

4. In a shovel-block for plows, the combi nationflvith astandard-journal having a perforated flange for suspending and retainingthe shovelblock, of a sleeve shovel-block adapted to rotate on thejournal and having a perforated flange, and a cotter or pin for lookingthe shovel-block after adjusting the same, substantially as and for thepurpose specified.

In testimony whereof I affix my signature, in presence of two witnesses,this 2d day of Jan nary, 1886.
